SAR Staff, Hasty Team, RAVEN, SVU, and WCSAR responded to Pyramid Lake to assist PLSAR and PL Police in locating a boater that was possibly having problems. A reporting party had observed the subject through binoculars from a good distance, towing his boat by swimming and having a rope around his waist. When PLSAR got in the area, nothing was located. Marine, Air, and Ground searchers were unable to locate a boat and/or the subject, although there was a truck with an empty trailer at the launch. Pyramid Lake SAR was going to check again in the morning.
